I want to build a raised bond out of lightweight blocks (left over from another build). The pond will be 1.8m x 1.0m and only x2 blocks high. Is this advisable? Will it hold? We will incorporate a waterfall which will overflow in to a small wildlife pond on ground level. Any help please, thanks

On the ground no I dont think it will, its very shallow, 2 blocks deep - whats that 8-10" max? I think the whole thing would freeze and expand to shift the light weight blocks out of line thus splitting any sheet liner? You will not be able to keep fish either at this depth they need at least 2.5 to 3ft to over winter.
